Abstract

East Kazakhstan Region is one of Kazakhstan's most industrialised regions, where emissions of pollutants from stationary sources remain a significant environmental risk factor for public health. Assessing the link between the structure of industrial emissions and disease incidence makes it possible to identify priority areas for prevention and environmental management.

The study was conducted based on official data on emissions of pollutants into the atmosphere from stationary sources (total volume, solid and gaseous/liquid components) and population morbidity indicators (neoplasms and diseases of the circulatory system) in five industrially loaded settlements in the East Kazakhstan region for 2020-2024. Spearman's rank correlation coefficient (rₛ) was used to assess the relationships, and statistical significance was assessed at p<0.05. The results were visualised using scatter plots.

Statistically significant positive associations were found between the incidence of neoplasms and total emissions (rₛ=0.633; p<0.001), as well as gaseous/liquid components (rₛ=0.552; p<0.01). The association between neoplasms and solid emissions was weak and statistically insignificant (rₛ=0.343; p>0.05). For diseases of the circulatory system, a significant association was found only with solid emissions (rₛ= -0.405; p<0.05), with no significant associations with total emissions (rₛ = -0.235; p>0.05) and gaseous/liquid components (rₛ = -0.285; p>0.05). A high correlation was noted between emission fractions (rₛ = 0.665-0.928; p < 0.001), indicating a common structure of industrial emissions.

The data obtained confirm the existence of a statistically significant correlation between emissions from stationary sources and the incidence of neoplasms in industrially polluted settlements in the East Kazakhstan region in 2020–2024.
